Hemipeplus mexicanus has the following diagnostic features: temples prominent and rounded (about 1/3 length of eye); scape submoniliform; eyes moderately large (as long as scape + pedicel), moderately wide and moderately convex; pronotum subcordiform, wide with deep anterior emargination; anterolateral angles produced, broadly rounded; pronotal pad very distinct, setose; posterolateral angles obtuse, rounded; pronotal lobe indistinct without median notch; scutellar shield transverse, subquadrate, about twice as wide as long; body elongate; elytra more or less flat; color rufotestaceous to rufopiceous; distribution: Guatemala, Mexico.

Male Genitalia (Figs 11D–F). (Tegmen length = 0.50 mm (n = 1)) Lobe of basale long, moderately thick, blunt at the apex; shoulders obtuse, rounded, slanted; apicale and basale with distinct suture; parameres depressed near the bases; apices of parameres very pointed and thin; penis slightly longer than tegmen.
